The purpose of this paper is to report on the development of a multi-transduction gas-sensor interface that is based on capacitive, resistive, and bulk acoustic wave (BAW) devices. The system is designed to be employed as a sensing hardware interface in the breath analysis for biomedical applications. The different transduction typologies are handled by means of electronic boards developed ad hoc. The prototype is compact and provides all the features needed for gas sensors characterization, from the electronic interfaces to the gas testing chamber, passing through the data acquisition system by a single board computer equipped by an Arduino DUE-compatible board. The developed system is very flexible and can be easily expanded to enhance its features through hardware or software upgrades.

Abstract

The purpose of this paper is to report on the development of a multi-transduction gas-sensor interface that is based on capacitive, resistive, and bulk acoustic wave (BAW) devices. The system is designed to be employed as a sensing hardware interface in the breath analysis for biomedical applications. The different transduction typologies are handled by means of electronic boards developed ad hoc. The prototype is compact and provides all the features needed for gas sensors characterization, from the electronic interfaces to the gas testing chamber, passing through the data acquisition system by a single board computer equipped by an Arduino DUE-compatible board. The developed system is very flexible and can be easily expanded to enhance its features through hardware or software upgrades. Here, we report the results of the preliminary activities regarding the measurement system development and its laboratory validation.
